WARNING
To avoid risk of electrical shock, personal injury or death, disconnect power to unit before servicing, unless testing requires
power.
Will Not Start
• Plug the unit into the wall outlet. Check for proper voltage.
• Check fuse or reset circuit breaker.
• Push any key to turn on the washer and press the Start/Pause key to run the washer.
• Close door and push the Start/Pause key to run the washer.
• Check if washer is in a pause, soak or suds process.
Wait briefly and it may start. (If the washer is in suds period, Suds will light up instead of remaining time.)
• Check for restricted drain system.
(If there is electrical problem in drain system, “nd” error will occur after 15 minutes.)
• Check Water Supply.
• Check the line or water valve screen filter.
• Check if PCB connectors are assembled properly.
• Check if CN5, CN6 terminals on PCB are in good condition.
(Refer to PCB Connector Check.)
• Replace PCB.
Leaking
• Start a normal cycle with the drum empty and fill her up to check its tumbling.
• Perform Quick Test Mode or Quick Spin Test
(Carry it out without laundry in the unit.)
• Check for loose connections at PCB, Water Level Sensor, Motor,
Hall Sensor Wire Harness, etc. (Refer to the Component Testing Procedure)
• Check motor windings resistance.
(CN9 1 & 3 = 11.6 ohms (±7% 20°C basis),
CN9 1 & 2 = 11.6 ohms (±7% 20°C basis),
CN9 2 & 3 = 11.6 ohms (±7% 20°C/68°F basis))
• If it doesn’t tumble after all of the above tests, change PCB. When the problem persists, change the motor.
No Tumble
• Start normal cycle with an empty machine and allow a fill to check tumble.
• Perform Quick Spin Test. (Before test, make sure that the tumbler is empty.)
• Check for loose connections at Machine Control Board, Pressure Switch, Motor, Tach Harness and Motor
Control. (Refer to the component testing procedure)
• Check motor windings resistance.
CN9 pins 1 & 3 = 11.6ohms ±7%,
Pins 1 & 2 = 11.6ohms ±7%,
Pins 2 & 3 = 11.6 ohms ±7%
• Faulty Main Control Board.
• Faulty motor.
Will Not Spin
• Make sure to close the door completely.
• Check for water left inside the washer. If so, go to “Will Not Drain”.
• Perform Quick Test Mode or Quick Spin Test.
Does the washer spin? (Before the test, empty the unit inside.)
If it doesn’t tumble after the above, change PCB.
When the problem persists, change the motor.
• Perform Quick Test Mode or Quick Spin Test.
Does the washer spin? If it does, Check Possible unbalanced load scenario in normal mode.
• Check for loose connections at PCB, Water Level Sensor, Motor, Hall Sensor Wire Harness. (CN8,CN9,CN3)
(Refer to the Component Testing Procedure.)
• Check motor windings resistance.
(CN9 Pin1&3 = 11.6 ohms (at ±7% 20°C/68°F),
Pin1&2 = 11.6ohms (at ±7% 20°C),
Pin2&3 = 11.6 ohms (at ±7% 20°C))
